Functional Nutritionist Specializing in Constipation & Bloat

Feel seen, supported, and symptom-free—with a proven system that addresses the root of your gut struggles.

You don’t need another elimination diet or random supplement.

You need someone who sees the whole picture and helps you actually heal.

I’m Leah Barack—functional nutritionist, gut health expert, and passionate about nervous system support, hormone balance, and helping women get rid of gut symptoms and enjoy food again without fear or restriction.

My work is for you if you’re ready to feel better and you’re tired of:

  • Chronic constipation or unpredictable digestion

  • Bloating, no matter what you eat

  • Digestive discomfort disrupting your days

  • Living in fear of food or your own body

  • Feeling confused about what to eat or which supplements (if any) you actually need

  • Being told IBS is just something you have to live with

  • Hormonal symptoms that no one’s explained or connected to your gut

Healing your gut changes everything — digestion, hormones, energy, even your relationship to yourself. You don’t have to figure this out alone.

Client Testimonials

  • A woman with shoulder-length brown hair smiling in front of a light-colored wall, wearing a black shirt and earrings, with a plant visible on the left side.

    Vickie S.

    “I can’t recommend Leah highly enough for her nutritional expertise—especially when it comes to bloating and constipation. After years of struggling with digestive issues and recovering from gallbladder surgery, I sought Leah’s help for targeted guidance on how to heal my gut and properly nourish my body.

    Her knowledge, compassion, and thoughtful approach made all the difference. Together, we created simple yet effective rituals that completely transformed my digestion. I’m now bloat- and constipation-free and feel confident in how to care for my body—even when unexpected food challenges arise.

    If you’re struggling with digestive health, don’t wait to ask for help. Working with Leah was truly one of the best gifts I’ve given myself.”

    Elise W.

    “After working with Leah, I’ve basically told every one of my family and friends about her. When we started, I had been dealing with bloating/discomfort for 3+ years and felt completely hopeless. I’d seen so many doctors and tried so many things, and was constantly given narrow, over simplified, one-size-fits-all advice that never actually helped. This was especially frustrating because over the years I’d learned a lot about digestion myself and could see how limited those approaches were.

    Working with Leah was the total opposite. She’s incredibly knowledgeable, kind, and resourceful, and she really centers your experience while bringing her own deep expertise. I’ve learned so much from her, and I’ve also seen a level of improvement I honestly didn’t think was possible after so many years.

    If you’re struggling with similar issues, I couldn’t recommend Leah more!!”

  • A woman with long, wavy light brown hair and light skin, smiling softly at the camera in an indoor setting with a brick wall background.

    "So thankful I discovered Leah! She has been so helpful and knowledgeable in guiding me through my digestive issues. I’ve dealt with bloating for decades now and no one has ever helped me so much, listened to me so well and been knowledgeable enough to navigate all the possible causes. I’ve never felt so much symptom relief and been so empowered to seek treatment and healing. Leah is a true gem and will meet you wherever you’re at. She’s realistic in her plans and goals and emphasizes progress over perfection. I highly recommend Leah!"

    “I came to Leah struggling with lifelong digestion issues. I had tried everything and doctors never gave me advice that moved the needle for me. Within a few weeks of working together, she has completely changed everything for me. I never thought I would be able to feel this great! My energy has improved, I can tolerate foods that used to cause me issues, and my digestion is the best it has ever been. I cannot say enough great things about working with Leah.”

    Katie G.

    I started working with Leah after having tried 3 other nutritionists to help with my chronic abdominal pain, bloating, and fatigue. I hadn't had any luck determining the root cause of my symptoms until my time with Leah! We were able to find out what was triggering my inflammation and it has completely changed my life. Leah's approach is gentle yet effective. Her recommendations have helped give me a solid foundation to building healthy habits. I am so grateful for her guidance and would highly recommend her to all!

    “I absolutely LOVED working with Leah! She created a personalized, holistic approach to address the issues that I was experiencing and needed help with. This approach helped me get to a place with greater understanding of my hormones, nutrition, and overall health, and ultimately it led me to feeling better than I’ve ever felt! In addition to the knowledge and expertise provided, Leah was kind, compassionate, supportive, incredibly responsive, and professional. Highly recommend!”

  • Rachel L.

    “Working with Leah has been such a pleasure! Not only is she super kind, but she is SO knowledgable and I love her holistic approach. I have a very complex health history, and Leah has been wonderful in looking over and explaining my labs, as well as recommending additional testing-- She is the reason I got my SIBO diagnosed!

    As someone who has had a lot of medical trauma with traditional western medicine, I was yearning for someone to look at me like a whole person. I have been in and out of doctors offices over and over again over the years, and so many things were not mentioned to me! I am always coming up with new questions or ideas, and Leah is so communicative in her responses.

    I HIGHLY recommend working with Leah at Grace Functional Nutrition if you are looking for a new approach and a caring practitioner!”

    Carol G.

    "Very professional, extremely knowledgeable, kind, patient, and compassionate. I couldn’t have asked for anyone better to work with on my nutrition journey. With Leah’s help I was able to significantly reduce inflammation, repair my gut, increase energy level, and generally feel sooo much better on a daily basis. Working with Leah was one of the best things I’ve ever done for my health and self-care. Highly recommend."
